Abstract: Systems and methods provide resource allocation signaling for low cost machine type communication (LC-MTC) devices with the elimination of the physical downlink control channel (PDCCH) in long term evolution (LTE) communication systems. Disclosed systems and methods provide alternative light-weight, efficient control signaling for resource allocation of LC-MTC devices.

Abstract: A 3GPP LTE protocol enhancement may realize the full benefit of dual connectivity in Long Term Evolution (LTE) networks by providing a mechanism to carry Radio Resource Control (RRC) messages and/or Information Elements (IE)s from a Secondary Evolved Node B (SeNB) to User Equipment (UE) via Master Evolved Node B (MeNB) RRC messages. Novel downlink (DL) Common Control Channel (CCCH) and Dedicated Control Channel (DCCH) messages, and augmented messages having Information Elements (IE)s for relaying RRC messages from a SeNB to a UE via a MeNB, are defined. Modifications to ASN.1 program coding of LTE 3rd Generation Partnership Project specifications to enable RRC messages from the MeNB to relay RRC information from the SeNB to the UE are provided. In one embodiment, the UE receives, from a MeNB, an RRC message comprising information relayed from a SeNB and interprets the RRC message for control channel and radio resource configuration information from the SeNB.

Abstract: Methods, apparatus circuitry, and storage media are described for mobile-terminated packet transmissions. In one embodiment, an apparatus of a control plane device configured to operate within an evolved packet network core identifies a first service flow event trigger associated with a first packet data unit (PDU) session and processes a path reselection for a first PDU session in response to the first service flow event trigger, wherein the path reselection determines a new gateway for the first PDU session resulting from the path reselection. Transmission of a change notification to an application server controller associated with the first PDU session is initiated in response to the path reselection. Transmission of a routing update to the new gateway in response to the path reselection is also initiated. In various embodiments, the trigger may be a mobility event, a load balancing event, or operations in association with an application server controller.

Abstract: In wireless communication networks in which pairs of STAs establish direct point-to-point links with each other, RTS-CTS training may be used to make sure that they don't interfere with other such pairs that communicate simultaneously during contention based access periods (CBAP). In some embodiments, two different types of CBAP are described for this. The PCP/AP may separately designate each type of CBAP for those devices using RTS-CTS training and those not using such training. In other embodiments, specific formats and fields are presented for communications involving these features.

Abstract: Embodiments of an enhanced Node B (eNB) and method to provide system information (SI) updates to user equipment (UE) in sleep or idle mode with an extending paging cycle are generally described herein. In some embodiments, a paging message configured to include an optional field to indicate whether there has been a system information (SI) update since a last paging occasion for a UE in sleep or idle mode with an extending paging cycle. System information updates are transmitted by the eNB during a system information modification period that is shorter than a period the extending paging cycle. The optional field may indicate whether or not the UE is to acquire the latest SI update during the current paging occasion.

Abstract: Technology for a user equipment (UE) operable to receive system information change notifications from an eNodeB is disclosed. The UE can receive one or more system information (SI) change notifications that indicate a change has occurred in one or more system information blocks (SIBs). The UE can receive a SIB1 that is associated with a value tag, and the SIB1 can include a bit-map that indicates which of the one or more SIBs include a change. The UE can compare the value tag associated with the SIB1 with a value tag stored at the UE. The UE can obtain scheduling information for the one or more SIBs that include a change according to the bitmap when the value tag associated with the SIB1 does not equal to the value tag stored at the UE. The UE can retrieve the SIBs that include a change using the scheduling information.

Abstract: Embodiments of an Evolved Node-B (eNB) to support Mission-Critical Machine Type Communication (MC-MTC) User Equipments (UEs) are disclosed herein. During a transmission notification (TN) monitoring period, the eNB may monitor for TN signals from MC-MTC UEs. When a presence of TN signals is detected, the eNB may refrain from allocation of dedicated MC-MTC traffic resources to other UEs for transmission during a traffic period. In response to a detection of an absence of TN signals from the first group of MC-MTC UEs during the TN monitoring period, the eNB may allocate the dedicated MC-MTC traffic resources to the other UEs for transmission during the traffic period. Starting times of the traffic period and the TN monitoring period may be spaced apart by a predetermined time difference. In some embodiments, the predetermined time difference for MC-MTC UEs may be not greater than 10 milliseconds.

Abstract: Embodiments disclosed herein relate to devices and methods that provide adaptive CRE-based offset parameters that take into account the speed of a UE and that take into account the DL/UL traffic balance being experienced by the UE. For example, if the speed of a UE is greater than the predefined speed, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Similarly, if the balance of downlink/uplink traffic being experienced by a UE is mainly downlink traffic, the UE utilizes an adaptive CRE-based offset parameter that has a low value or is equal to zero. Consequently, the embodiments disclosed herein reduce the handover failure associated with CRE particularly for high speed UEs while also being able to increase downlink system capacity if the balance of the downlink and uplink traffic experienced by the UE is mostly downlink traffic.
